LINE-CASTING MACHINE.

SEECIFIGATION forming part of Letters Patent N 0. 733,559, dated July 14, 1903.

Application filed October 16, 1901. Renewed November 5, 1902. Serial No. 130,149. (No model.)

To all whom it may concern:

Be it known that I, WILBUR STEPHEN Scon- DER, a citizen of the United States, and a resident of Brooklyn borough, New York, State of New York, temporarily residing at Montreal, in the county of Hochelaga and Province of Quebec, Canada, have invented certain new and useful Improvements in Line- Casting Machines; and I hereby declare that the folro lowing is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in that class of linecasting machines known as the monoline,

which is fully described in my Letters Patent of the United States No. 506,198, dated Octoher 3, 1893, and No. 605,141, dated June 7, 1898, and to which reference is made.

My present invention relates to certain new and useful improvements in the pot in which the type-metal is melted and in the mold for casting lines of predetermined length an thickness.

ZVIetal-pot.At present in line-casting ma- 2 5 chines the metal-pot is made of a solid casting on account of the variable shapes that it is necessary for it to assume to accommodate the predetermined space in the machine and also for reasons of economy in its manufac- 3o ture. By reason of the heavy strain of the large store of metal carried therein and the numerous variations of temperature to which the metal-pot is daily subjected the cast-iron does check and from time to time form leaks 3 5 which seriously interfere with the successful operation of this part of the machine. This is more pronounced in the lighting up. lVhen a full flame is turned on the pot filled with type-metal, the metal nearest the flame 0 becomes heated, expands, and forces the castiron of the pot to expand before the typemetal at the top of the pot becomes fluid. To overcome the difficulty occasioned by this unequal expansion and contraction, I have con- 5 structed the metal-pot of one piece of sheetsteel pressed into the desired shape, the sides and ends of the pot being provided with vertical corrugations extending from the bottom to the top, which by expanding laterally relieve the sides and ends of the pot of the strain carried by the longitudinal and unequal expansion that takes place as the metal is being heated, thus preventing the checking andsubsequent leaking of the pot.

llI0Zd.In line-casting machines using a laterallymoving mold but one aperture has heretofore been provided, it being the custom when other measures were required to take out the mold-box and insert another one containing the desired measure. This invention provides a mold-box which will have a plurality of apertures for casting lines of predetermined length and thickness and aframe in which the mold-box is carried movable at right angles with the fixed travel of the mold, thus allowing the mold-box to be adjusted from one position to another to bring into play the predetermined aperture.

For a full understanding of my invention reference is had to the accompanying drawings, forming a part of this specification, in which like symbols indicate the same parts, and wherein I Figure 1 is a front View of the mold-slide of the monoline-machine to which my invention is applied. Fig. 2 is asectional view on the line a b in Fig. 1. Fig. 3 is a plan View of the several parts, and Fig. 4 is a sectional view on the line 0 (Z of Fig. 3. Fig. 5 is a perspective view of the cam-ring for adjust ing the position of the supporting-block. Fig. 6 is a view of the supporting-block, showing it and the cam-ring in the position shown in Fig. 1. Fig. 7 is a similar view to Fig. 6, showing the cam-ring and supporting-block in their alternative position.

MetctZ-pot.-The Letters Patent heretofore referred to show merely a cast-iron pot of an oblong shape within a protecting jacket, which jacket acts both as a protector for the other parts of the machine to keep the heat confined and as a frame through which the pressure of the pot-cam is conveyed to the front of the machine and applied to the mouth of the metal-pot to properly lock it against the mold to prevent leakage of metal at the instant of casting the line. My new pot 1 does not alter any of these conditions, but substitutes for the cast-iron pot a pressedsteel pot 1, the sides and ends of which are provided with corrugations 2 and corner-folds 3. While I am fully aware that the pressing of sheet metals into desired shapes is well known to the trade, yet as applied for use in machines of this class it presents a marked the type-metal.

Compound mZd.In the accompanying drawings the mold-slide is constructed in the usual manner, the top half or section 1 and the bottom section being separated at their outer or free ends by the separating-block 6, the opposite ends of the sections being attached to the supporting-block 7, pivoted on the mold-slide stud 8. At the base of the mold-slide stud 8 is placed a cam-faced ring 9, supplied with a lever 10 to facilitate the adjustment of the cam-faced ring 9. In the separating-block 6 I have shown two slots 11, in the upper one of which is fitted a removable guide-piece 12, suitably attached to the upright knee 13. The completed slide, as shown, thus forms a frame which can be swung on the stud 8, its outer or free end being guided and supported by the guide piece 12. By the temporary removal of the guide-piece 12 and the turning of the camfaced ring 9 the entire slide can be shifted to another position as much higher as the thickest part of the cam-faced ring 9 will give. The guide-piece 12 can be then replaced in the corresponding slot 11 and the new position of the slide made secure. Traveling laterally in the opening formed by the two sections 4 and 5 of the mold-slide is the mold-box 14, motion to which is imparted through the link 15 and the lever 16. In the mold-box I have shown two apertures 17 and 18 for castinglines, the upper one, 17, of which is in position for casting. In Fig. 2 I have shown in dotted lines the mold 14 and the mold-slide shifted to the upper position, thus bringing the lower mold 18 into position for casting. Near the mold-slide stud 8 of the mold-slide I have attached to the lower section 5 of the mold-slide a bracket 19 on the front side of the same, which is suitably formed to carry the trimming-knives 20. Directly opposite and attached to the lower section of the mold-slide 5 is the bracket 21, which is provided with a dovetailed slide 22, upon which is mounted two ejector-blades 23. The rear end of the slide 22 has a tenon formed therein, 24, which is fitted loosely in the mortise formed in the ejector-slide 25. This ejector-slide 25 is similar to that in use on the monoliue and takes motion in the same manner through the ejector-fork 26 and the cam 27. In order to give motion at proper intervals to the free end of the mold-slide, the bracket 28 is attached thereto and is connected by a link 29 to the bracket 30, attached in turn to the pot-jacket 31. The potcam 32 is provided with steps to impart motion to the jacket 31 and through it to the connecting parts.

The operation of the mold-slide is similar to that described in the Letters Patent heretofore mentioned, the improvement consistingof means provided for shifting the entire mechanism to a new position, which brings into play any predetermined aperture in the mold-box l t for casting the line and with it its own means for ejecting and trimming the line-bar so cast. It will be appreciated that the mold-slide may be enlarged and arranged to receive a larger mold-box 14:, which would have a varied assortment of apertures for casting lines therein, than I have shown and be as easily and readily shifted to the diiferent positions in the same manner as that above described. The connecting and moving mechanisms require no changing or positioning whatever, sufficient play being provided between the ejector-bracket 21 and the fixed part of the bed-plate carrying the slide 25 and in the connection 24 and between the bracketslide 22 and the fixed slide 25 to permit the swing of the frame necessary in the operation of the machine. The knife-bracket 18 and the ejector-bracket 21 are rigidly affixed to the lower section 5 of the mold-slide and are, for mechanical purposes, a part of it. The ejector-blades 23, the mold-slots 17 and 18, and the trimming-knives 20 all bear toward each other fixed relations and are arranged to provide each aperture in the mold-box 14 with its own means for ejecting and trimming the bar cast.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
